No Skin, No Advice
The rule
Never act on advice from someone who pays no price if they are wrong. A tip is cheap when the tipster loses nothing.
Where it flips
This rule can make you reject every free lesson, yet many honest teachers and writers share good method with no stock to push. The fix is to separate real knowledge, which you can check yourself, from specific buy-and-sell tips, where paying a price for being wrong matters most.
Talk is cheap when it is only talk. A tipster, TV anchor or forum hero who suffers nothing when the call fails has no reason to be careful, so their confidence is free and worth little. The advice worth weighing comes from people whose own money moves the same way as their words. If they pay no price for being wrong, take what they say lightly.
A worked example
A TV guest calls a stock a 'sure double' at ₹800. It falls to ₹450. He keeps his fee and airtime, while Aman, who acted on the tip, carries the whole loss alone. [illustrative]
How to spot it
- ·A loud tip with no personal stake behind it
- ·No answering for past calls that failed
- ·Confidence that costs the speaker nothing
