We show 66 historical shares outstanding datapoints in our ITW shares outstanding history coverage, used to compute ITW market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing ITW market cap history over the course of time is important for investors interested in comparing ITW's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of ITW versus a peer is one thing; comparing ITW market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like ITW can fluctuate over the course of history.
