Some strategies about buying stocks

In a post last week, I had discussed strategies for selling stocks. Most small investors know how to buy stocks, but they rarely have proper strategies for selling. So why am I writing about buying strategies?

From the spate of questions I have recently received about when and how much to buy, it seems that discussing some buying strategies may be useful after all. I had mentioned about using the ‘Margin of Safety’ concept and P/E bands to decide entry points in last week’s post.

The importance of those two concepts can’t be over-emphasised. Too many young investors follow the wild west policy of ‘Shoot first, and ask questions later’. Just switch on any business TV channel (just for entertainment) during the day when they take reader queries. 99% of the questions are: ‘I have bought thus and such stock at this price; should I hold or sell.’

It is apparent from the questions that the stock was bought near a top, and the investor is already sitting on a loss. The question – or rather, a plea – is to find out if the TV expert knows some magical formula by which the loss can be quickly turned into a profit, or, at worst, break-even with no loss.

All one has to do before placing a buy order, is to first check whether the current E/P (i.e. inverse of the P/E ratio) is higher than the long-term bank fixed deposit rate, leaving a ‘Margin of Safety’ . Also check that the debt/equity ratio is less than 1, and that the cash flow from operating activities is positive for 4 of the last 5 years.

If E/P is lower than the bank FD rate, then check the P/E band within which the stock normally trades, and buy only if it is available near the middle of the P/E band or lower. These are basic precautions, and will help prevent losses – even if you don’t have the time or inclination to do a detailed fundamental analysis.

If you are like most small investors, the stock price will fall just after you’ve bought it (and, it rises soon after you sell)!! What should you do? Do not, repeat, do not average down. That is the single cause for turning a small loss into a much bigger one. Instead, keep a stop-loss – and sell if the stop-loss is hit on a closing basis (i.e. take intra-day movements out of the equation).

You will make much more money by averaging up. When should you do that? Buy 20-25% of your intended quantity at the beginning. Add more every time the stock dips or corrects on the way up. Follow a ‘pyramid’ strategy – i.e. buy less and less quantity on the dips as a stock keeps moving up in price – till you acquire your intended quantity.

Such a strategy will prevent impulsive buying of 2000 or 5000 shares in one go, in the hope of becoming a Warren Buffett within a month. Talking of Buffett, I love his quote: ‘You can’t make a baby in one month by getting nine women pregnant!’

Wealth-building takes time. If you hone your buying and selling strategies, you have a chance of becoming wealthy in 15-20 years – but not in 15-20 months.
