日経平均株価をわかりやすく簡単に解説

日経平均株価は、東証一部(東京証券取引所一部市場)に上場している銘柄のうち主要225銘柄の単純平均株価です。TOPIX(トピックス)と並んで日本を代表する株価指数となっています。単純平均株価とは、株数などでウェイト付けしていない平均株価で、対象銘柄の株価合計を対象銘柄数で割って算出される平均株価です。株価の合計を銘柄数で割って求める単純な平均株価ですので、225銘柄のうち値がさ株(株価が高い銘柄)の影響を受けやすい特徴があります(厳密には連続性を保つために修正が加えられている修正平均株価です)。つまり日経平均株価の寄与度が高い銘柄の値動きの影響を受けやすいです。そのため全体の株価動向を見るには適しておらず、全体が強い相場であっても値がさ株が弱ければ日経平均株価は弱い動きをしやすくなります。ただし、一般的には認知度の高さやわかりやすさなどから、日本の株式市場全体の動向を見る際に見られる株価指数です。日経平均株価の構成銘柄は、10月初めに産業構造の変化に合わせて入替が行われます。

TOPIX(トピックス)をわかりやすく簡単に解説

TOPIX(トピックス)は、東証一部全銘柄を対象とした株価指数です。日経平均株価と違って時価総額でウェイト付けした株価指数ですので、マーケット全体の動きを見るには適しています。一方、時価総額が大きい銘柄(大型株)の動きに左右されやすい特徴があるため、トヨタなどの値動きに左右されやすい株価指数です。つまり、TOPIXが強ければ大型株が活況であるため、大型株中心の投資が有効になりやすいです(日経平均株価が強い場合は値がさ株が活況ですので、値がさ株中心の投資が有効になりやすいです)。日経平均株価が強いかTOPIXが強いかを示す指標として「NT倍率」がありますので、合わせてチェックしておくと投資が効率的になりやすいです。

NT倍率の推移(チャートと時系列)と解説は、以下のページで掲載してるよ!

NT倍率
日経平均とTOPIX(トピックス)の倍率「NT倍率」のチャートと時系列です。上昇・低下の意味と使い方を解説。NT倍率は値がさ株と大型株の強弱を示し、急落のリスクが計れ、ヘッジファンドの動きを探ることができます。裁定買残と合わせて見ましょう。

JPX400をわかりやすく簡単に解説

JPX400(JPX日経インデックス400)は、東証(東京証券取引所)の上場銘柄の中からROE(自己資本利益率)を基準に、投資魅力の高い銘柄4000を選別した日本の代表的な優良株400社の株価指数です。ROEの高い銘柄は外国人投資家が好みますし、優良株で構成されていますので、相場が弱い局面の時も比較的株価が底堅く推移しやすい特徴があります。TOPIXは赤字企業も入ってしまいますので、下落局面の際はJPX400より弱い動きとなりやすいです。

2021年の日経平均株価・TOPIX・JPX400の時系列データ

2020年

2020.10.1 東京証券取引所(東証)の情報系システムでシステムトラブル。終日全銘柄が売買停止になりましたが、日本化薬株式会社とソフトバンクの日経平均銘柄入れ替えに伴う除数の変化分が反映され、日経平均株価は19銭安で値が付いていますが、2020年10月1日の日経平均株価は算出されていません。

東証のシステムは株式売買システム「アローヘッド(arrowhead)」と株価情報などを配信する情報系システムがあり、情報系システムに障害が発生。

[追記(2020年10月2日)]日経平均株価の2020年10月1日の終値について、日本経済新聞社は2020年9月30日と同じだったとみなすと発表しました。
