日経225全銘柄の投資効率を検証 |
https://qiita.com/MandT500/items/f4aaafa0de824dab92c2
|
日経全銘柄の投資効率を検証株式投資で資産運用をするときできるだけ少ない資金でできるだけ小さいリスクで利益を出していきたいと投資の効率性を考えます投資の効率性はリターンとリスクによって決定されますしたがって効率的な投資戦略を考えるうえで重要となるのは投資によるリターン株価収益率投資に伴うリスク収益率の分散の理解とリスクに見合うリターンシャープ・レシオが得られているかですどの指標も高校数学までのレベルで数理ファイナンスの世界では基礎的なものです本記事ではこのつの指標について理解し日経全銘柄について投資の効率性を検証しました投資によるリターン株価収益率まずはじめに収益の効率を考えるうえで重要となるのは投資金額に対する収益額の割合収益率です例えば株円の株券Aを株購入し翌日に円になったときに売却すれば円の収益を得ることができます一方株円の株券Bを株購入し翌日に円になったときに売却すれば株券Aと同じ株当たり円の収益を得ることができます株あたりの収益額でみるとどちらも同じ利益を得ています一方で収益の効率を考えたとき株券Aでは円を投資して円の利益を得られているのに対して株券Bでは円も投資したのに円の利益しかえられていません円もあれば株券Aを株購入し収益を円を得られることができていましたあるつの株券の銘柄についてt期目の株価をStとするとt期の株価収益率rはrfracStStStによって計算することができますこれは投資金額単位に対する収益額を意味しますこのとき上で定義した株価収益率によって株券Aと株券Bの投資効率rAとrBを計算するとrAfracrBfracとなりますしたがって株券Aは株券Bの倍投資効率が高いことがわかります下の表は三菱自動車とJT日本たばこ産業の株価を年月日から月日までを日ごとに集計したものですYahooFinanceから得た株価データです株価のとなりに日ごとの収益率も計算しています右のグラフは株価データを基に作成した各社の株価の推移のグラフです各社の収益率の平均について三菱自動車はJTはとなりますこの平均値を近い将来の期待できる収益率と考えると月は三菱自動車に投資する方がJTに投資するよりも大きなリターンが期待できるといえます投資に伴うリスク収益率の分散投資におけるリスクは不確実性収益率の分散という意味ですつまり損失の可能性と利益の可能性はどちらもリスクといいますリスクが高いというのは損失の可能性が高いということに加えて利益の可能性も高いということを意味します三菱自動車とJTの日ごとの収益率をグラフにすると以下のようになります三菱自動車は収益率の変動が大きく大きく損をする可能性も高いが大きく利益を得られる可能性も高いことがわかりますJTは三菱自動車よりも変動が小さいので大きく損をすることも少ないが大きく利益を得られる可能性も少ないということがみて理解できると思います三菱自動車は収益率の変動が大きいJTは変動が小さいこれを測定するには収益率の分散標準偏差を調べますこれがリスクの指標となります収益率の分散はN個の収益率データXXXXNに対して平均をEXとすると分散VXはVXfracNsumiNXiEXと定義されますこれを用いて社の収益率の分散を計算すると上の表にも示した通り三菱自動車はJTはとなりますしたがってこの数値を比較しても三菱自動車はリスクが高くJTはリスクが低いことがわかります投資の効率性シャープ・レシオ株価収益率は投資金額に対してどれくらい収益が得られたかがわかりましたしかし、各銘柄の株価収益率の比較では、投資家がとるリスクが考慮されていません「リスクに見合うリターンを得ているか」という投資効率はシャープ・レシオという指標を使って数値化することができますこの数値が大きいほど、小さなリスクで大きな投資リターンを上げたことになります例えば、株券ABともにある期間において平均リターンがだったとしてもAはリスクの大きい商品標準偏差Bはリスクの小さい商品標準偏差であれば、Aのほうが効率の良い投資結果といえます。 |

Traffic Director takes application networking beyond Google Cloud |
https://cloud.google.com/blog/products/networking/traffic-manager-extends-its-service-mesh-to-non-gcp-endpoints/
|
Traffic Director takes application networking beyond Google CloudWhether you run services in Google Cloud on premises in other clouds or all of the above the fundamental challenges of application networking remain the same How do you get traffic to these services And how do these services talk to each other Traffic Director is a fully managed control plane for service mesh and load balancing We built Traffic Director with the vision that it could solve these challenges no matter where your services live Today we re delivering on another part of that vision so that we can better support your multi environment needs With Traffic Director you can now send traffic to services and gateways that are hosted outside of Google Cloud Traffic is routed privately over Cloud Interconnect or Cloud VPN according to the rules that you configure in Traffic Director This capability enables services in your VPC network to interoperate more seamlessly with services in other environments It also enables you to build advanced solutions based on Google Cloud s portfolio of networking products such as Cloud Armor protection for your private on prem services Whether you re only running workloads in Google Cloud or have advanced multi environment needs Traffic Director is a versatile tool in your networking toolkit Introducing Hybrid Connectivity NEGsThis is all made possible through support for Hybrid Connectivity Network Endpoint Groups NEGs Now generally available think of a Hybrid Connectivity NEG as a collection of IP addresses and ports endpoints that clients can use to reach your application You probably already use NEGs when configuring Traffic Director with GKE based services Hybrid Connectivity NEGs are special because they don t need to resolve to a destination within Google Cloud Instead they can resolve to a destination outside of your VPC network like a gateway in an on prem data center or an application on another public cloud If you re sending traffic from Google Cloud to another environment that traffic travels over hybrid connectivity for example Cloud Interconnect or Cloud VPN This allows you to have workloads in another environment and reach them securely from Google Cloud without having to make those workloads accessible via the public internet Here s a simple example of how you might use Hybrid Connectivity NEGs with Traffic Director Imagine you have a virtual machine VM running on prem and that VM can be reached from your VPC network via Cloud VPN interconnect at on port In Traffic Director you create a service called on prem service and add a Hybrid Connectivity NEG with an endpoint with IP address and port Traffic Director then sends that information to its clients for example Envoy sidecar proxies running alongside your applications Thus when your application sends a request to on prem service the Traffic Director client inspects the request and directs it to What can I do with it With this feature you can now build powerful solutions that involve existing Traffic Director capabilities as well as Cloud Load Balancing s global network edge services Here are a few examples Route mesh traffic to on prem or another cloudThe simplest use case for this feature is plain old traffic routing For example You want to get traffic from one environment to another In the above example when your application sends a request to the on prem service the Traffic Director client inspects the outbound request and updates its destination The destination gets set to an endpoint associated with the on prem service in this case The request then travels over VPN or Interconnect to its intended destination If you need to add more endpoints you just add them to your service by updating Traffic Director You don t need to make any changes to your application code Migrate a service between environmentsBeing able to send traffic privately to an endpoint outside of Google Cloud is powerful But things get even more interesting when you combine this with Traffic Director capabilities like weight based traffic splitting The above example extends the previous pattern but instead of configuring Traffic Director to send all traffic to the on prem service you configure Traffic Director to split traffic across two services using weight based traffic splitting Traffic splitting allows you to start by sending of traffic to the cloud service and to the on prem service You can then gradually increase the proportion of traffic sent to the cloud service Eventually you send of traffic to the cloud service and you can retire the on prem service Use Google Cloud s edge services with workloads in other environmentsFinally you can combine this functionality with Cloud Load Balancing to bring global edge capabilities to workloads that are outside of your VPC network Cloud Load Balancing offers a wide range of network edge services such as globally distributed ingress Cloud Armor for DDoS protection and Cloud CDN You can now use these with Traffic Director to support workloads that are not exposed to the public internet if you have Cloud VPN or Cloud Interconnect between Google Cloud and another environment your traffic will travel via that private route We previously posted about how you can use Cloud Armor with on prem and cloud workloads that can be reached via the public internet In the approach described below workloads in other environments don t need to be publicly reachable In this example traffic from clients travels over the public internet and enters Google Cloud s network via a Cloud Load Balancer such as our global external HTTP S load balancer You can use network edge services for example Cloud Armor DDoS protection or Identity Aware Proxy user authentication when traffic reaches the load balancer After you ve secured your ingress path the traffic makes a brief stop in Google Cloud where an application or standalone proxy configured by Traffic Director forwards it across Cloud VPN or Cloud Interconnect to your on prem service Get started todayWith Traffic Director we ve been focused on enterprise needs since day one and we re excited about the class of problems that Hybrid Connectivity NEGs solve for enterprises that operate beyond GCP Get started today with Traffic Director Google Cloud Load Balancing and Cloud Armor to set up a secure global ingress solution for private multi environment workloads This is just a first step on our journey to delivering on Traffic Director s mission of being a truly universal application networking solution More to come Related ArticleGoogle Cloud networking in depth How Traffic Director provides global load balancing for open service meshGoogle Cloud s new Traffic Director control plane management tool brings load balancing
