Dos and Don'ts

Do not hold stocks before their 決算日.

The 決算日 of 島精機製作所 is scheduled on the 28th and its recent stock price is　going up almost everyday.

After a negative 決算 forecast was released in the afternoon, the stock price was dropped sharply.

Although I mistakenly sold this stock on Monday, it turned out to be good.

I have three more brands whose 決算日 are scheduled next week.

I can hopefully sell them at satisfactory values this week.
