We're seeing the exact same setup in shares of Prudential Financial ( PRU). Like L Brands, Prudential is forming a double top -- in this case with a breakdown level at $75. If that price gets violated, it's time to sell PRU. >>5 Stocks Insiders Love Right Now Whenever you're looking at any technical price pattern, it's critical to think in terms of those buyers and sellers. Double tops, triangles, and other pattern names are a good quick way to explain what's going on in a stock, but they're not the reason it's tradable. Instead, it all comes down to supply and demand for shares. That support level at $75 is a price where there had been an excess of demand of shares; in other words, it's a place where buyers were more eager to step in and buy shares at a lower price than sellers were to sell. That's what makes a breakdown below $75 so significant -- the move would indicate that sellers are finally strong enough to absorb all of the excess demand above that price level. That's why it makes sense to wait for that indication before you sell.
