Reading, "The Intelligent Investor", for short term trades would yield little value because there is a distinction made by the author between trading and investing.

Investing: An operation that, upon thorough analysis, promises the safety of principal and an adequate return. Investments are typically long-term and involve holding securities that are undervalued by the market. The investor views a stock as part ownership of a business and looks to the actual performance of the business to drive the return on their investment.

Trading/Speculation: Trading, or speculation, on the other hand, does not meet the criteria of thorough analysis, safety of principal, and an adequate return. Speculators are primarily concerned with price movements and often look for short-term gains. They treat stocks as mere pieces of paper and are less concerned with the underlying business’s fundamentals.

This is why value investors have tended to outperform over the long term VS the casinofication of the current market (especially your average trader who underperforms the market). Which likely leads to the indifference of valuation you've suggested. And slowly but surely valuation will be found, hence the existence of bubbles. Us humans have a hard time thinking in such scopes of time.
