日経平均株価の月間騰落率をまとめた表。日経平均は1949年5月に算出が始まったため、1949年6月以降の騰落率を表にしている。
1989年以前以後
日本株は戦後、1989年12月29日に大天井を付けるまで40年間にわたる大相場が続いた。日経平均の史上最高値はこの日つけた3万8957円44銭。1990年にバブルが崩壊し、その後20年以上高値を更新できずにいる。1989年以前と以後で騰落の傾向は大きく変わる。

| 1949年6月～1989年12月 | 299カ月 | 188カ月 | +4.49% | -3.86% |
| 1990年1月～2011年4月 | 125カ月 | 131カ月 | +4.82% | -5.23% |
1949年6月から1989年12月までの487カ月間で、日経平均は299カ月が前月比で上昇。下落は188カ月。上昇月となる確率は61.4％。
1990年1月以降、2010年3月までの243カ月間では上昇が118カ月、下落は125カ月。日経平均が1989年12月の終値3万8915円87銭から2010年3月終値1万1089円94銭まで大幅に下落していることを考えると、上昇月は意外なほど多い。
これは、別の角度から見ると、上昇は緩やかだが下落は激しいことの表れとなる。1990年以降、上昇となった月の平均上昇率は4.90％で下落月の平均下落率は5.22％である。10％の下落で失った資産を取り戻すためには約11.1％の上昇が必要となる。平均上昇率4.90％と平均下落率5.22％の差は見た目以上に大きい。100万円の資産が1カ月目に4.90％上昇し、2カ月目に5.22％下落するという動きを1年間繰り返すと、1年後には96万5946円となる。10年後には70万7182円まで減少している。
