Citing legendary investor Peter Lynch, Cramer warns that an exceptionally low price-to-earnings ratio is often a red flag, not a value play. The market is correctly pricing in a future collapse of earnings. He uses the example of Bethlehem Steel, which traded at 2x earnings just two years before going bankrupt.

Despite clear bullish signals like deregulation and a capital markets recovery, investors have hesitated to commit to financials, creating an under-owned sector. This sets the stage for a potential 'catch-up' trade, especially for regional banks positioned to regain market share.

Contrary to viewing fiscal constraints as a negative, Morgan Stanley highlights that European banks are positively exposed. Tighter government spending tends to steepen the yield curve, which directly boosts bank profitability. This, combined with low valuations and consistent earnings beats, makes the sector a top pick.

Despite managing a financials fund, Derek Pilecki is bearish on the average bank. He argues that intensifying competition from online banks and giants like JP Morgan will continuously compress margins and lower returns over the long run, making passive bank investing a poor strategy.

Templeton sought stocks so unloved they were like books in a dusty basement corner nobody visits. Actionable signals of such neglect include zero institutional ownership or IR departments that haven't received calls from investors in years. This is where the greatest price inefficiencies are found.

Rainwater's method was to find a great business with poor management, acquire a stake, and then use his influence to install a world-class leader. He did this with Disney by bringing in Michael Eisner, believing the 'fix was just really easy. All he had to do was change the CEO.'

Anchoring valuation on a company's typical price-to-sales ratio helps identify buying opportunities when margins are temporarily depressed. This avoids the pitfalls of methods like the Magic Formula, which can mistakenly favor companies at their cyclical earnings peaks, leading to underperformance.

A tender offer, where a company buys a large block of its stock in a set price range, signals higher conviction than a typical buyback program. It forces management to put a stake in the ground, indicating they believe the shares are significantly undervalued at a specific price.

Instead of complaining that its stock trades at a steep discount to its net asset value (NAV), Exor's management pragmatically views this as a chance to invest in themselves. They trimmed their highly appreciated Ferrari stake specifically to fund share buybacks at this significant discount.
