After the bubble burst, the Nikkei Stock Average dropped from the 0.03 million yen range to the 7,000 yen range over a decade. At that time, I bought stocks hoping to invest, but ended up losing money. Eventually, I realized that short selling was more profitable. From such a rock bottom situation, over another decade, the Nikkei Stock Average reached the 0.04 million yen range. I think it was largely thanks to monetary easing.
