Ten-baggers

When Priya was small, her family planted ten tiny fruit saplings behind their house. Most stayed small. A few died. But one guava sapling grew and grew until it became a huge tree that fed the whole street every season. If, in the second year, someone had said "these plants are boring, let's dig them all out," they would have lost that one giant tree forever.

Here is the strange thing. That one great tree gave more fruit than all the others put together. Losing the weak plants cost almost nothing. Losing the one giant would have cost everything.

Peter Lynch found the same truth in companies. He called a share that grows to ten times its price a ten-bagger. ("Bagger" is a cricket-and-baseball word - a ten-bagger is like hitting the ball all the way for a huge score.) Lynch said you do not need many of these in a whole lifetime. You need just a few, and you need to not cut them down too early. This study is about spotting a possible giant - and, even harder, having the patience to let it grow.

A share is one small piece of a company; its price is what one piece costs to buy today. If you buy a share at ₹50 and it later becomes ₹500, that is a ten-bagger - ten times, or "10×".

Most people do the opposite of Lynch's advice. When a share doubles, they feel clever and sell it to "book the profit." It feels safe. But if you sell every winner at 2×, you can never get a ten-bagger - you cut every tree down when it is still a shrub. Meanwhile you often hold on to your losing shares, hoping they come back. So people sell their guava tree and keep their dead saplings - exactly backwards.

Lynch's read is this. In a basket of shares, a few will do badly and a few will do wonderfully, and the few wonderful ones can pay for all the rest and then some. A single ten-bagger can make up for many small losses, because a loss can only take away what you put in (say, ₹100), while a winner can multiply it many times over (₹100 becomes ₹1,000). The most important skill, then, is not just finding a giant. It is having the patience to let a winner run instead of snipping it at the first small profit - as long as the reason you bought it is still true and the business is still growing.

illustrative Suppose Kabir puts ₹100 into each of five different shares - ₹500 in all. Watch how it can end.

Two of them fall and become worth ₹50 each. One stays flat at ₹100. One grows nicely to ₹200 - a double. And one, a small fast-growing company called Sunrise Shop that keeps opening new branches, quietly becomes a ten-bagger: his ₹100 turns into ₹1,000.

Add it up. The two losers gave back only ₹100 together. The flat one is still ₹100. The double is ₹200. And the one giant is ₹1,000. His ₹500 has become ₹1,400 - nearly three times - and almost all of that came from the single ten-bagger. Now imagine Kabir had sold Sunrise Shop at ₹200 to "book profit." He would have lost the whole giant and been left with a very ordinary result. The losers cost him little. Selling the winner too soon would have cost him almost everything. That is Lynch's lesson in numbers.

"Let it run" is not "never look again." Holding a winner is right only while the reason you bought it is still true. If the business stops growing, the shop empties, or the story breaks, patience turns into stubbornness. Lynch held winners, but he kept re-checking the story; he did not just shut his eyes and hope.

Most shares are not ten-baggers, and you cannot know in advance which is. For every giant tree there are many that stay small or die. Chasing a ten-bagger by buying wild, risky companies is a good way to lose money. The giants tend to be found among honest, growing, understandable businesses - not lottery tickets.

A ten-bagger takes years, and the ride is bumpy. A share on its way to 10× will often fall halfway along, scaring people out. Real patience means sitting through the scary dips, which is far harder than it sounds. Many people who "would have" held a giant actually sold in fear during a dip.

The idea travels well, but two Indian cautions matter. First, a ten-bagger is only worth it if the business truly grows for years - not if a crowd simply pushes the price up in a few excited months. A price that jumps ten times on hype, not on real growing profit, is a bubble, and bubbles fall back down. Second, patience must never become blindness. In our markets you will see small companies rise fast and then collapse just as fast; "letting a winner run" applies to a genuinely improving business, not to a rumour. So use the guava-tree lesson to stop yourself snipping good trees too early - but keep checking that the tree is still healthy, still growing fruit, and not hollow inside.

• Don't sell a winner just because it doubled. Ask instead whether the business is still growing and the reason you bought it is still true.
• Water the flowers, pull the weeds. People do the opposite - they sell winners and cling to losers. Notice if you are doing that.
• Remember one giant can carry a whole basket. A loss can only take what you put in; a winner can multiply it many times.
• Look for ten-baggers among growing, understandable businesses, not among wild rumours and lottery-ticket shares.
• Expect a bumpy ride. A future giant will dip scarily on the way up; plan to sit through the dips if the story holds.
• Write down the reason you own it. When you are tempted to sell, re-read it - sell if the reason broke, hold if it did not.
