Over the past days I have been contemplating the US - and to some extent the world - automotive industry. Henry Ford's great accomplishment was in emplacing the concept of production line manufacturing in a large-scale industry; the result was that the automobile could be priced at a level affordable to more than the top 1% of American consumers (is there something in that that sounds familiar, people?)/ William Durant's great accomplishment was in establishing a vast nationwide, then worldwide, network of sales platforms, and combined with innovations in automotive financing, led General Motors to surpass Ford by the end of the 1920s. Walter Chrysler's great accomplishment was to take an implacable drive for engineering excellence and combine that with a spectrum of low- to high-priced cars. Chrysler overtook Ford in the mid-30s and held the #2 slot until about 1950. So - for those of you with access to really long-term financial data - it's hard for me to snag that stuff out here in the middle of nowhere - I think it would be a fun, and potentially useful, exercise to see where these three giants have stood at their respective peaks. Some criteria could be: 1. largest market capitalization, gross 2. peak capitalization wrt overall market (S&P 500 capitalization would be the most tractable long-term data, I should think) 3. presence - possibly with market cap as the datum, possibly with sales as % of GDP as the metric - within the overall US economy and, (you knew this was coming) where Tesla would have to stand in order to reach the marks above. Ford's data will be a little difficult to come by, as the company remained closely held until the late 50s and early 60s, when, through a series of then-innovative steps, stock was slowly released from both Ford Foundation and Ford family members, automatically shifting from Class A to B as it became publicly traded. So I'm not sure how one appropriately could place a market cap on F stock in earlier decades. Anyone interested in the exercise? It's the sort of stuff that would entrance me in prior times, but I've still got lots of snow to shovel and roofs to clear and plumbing to de-thaw....this has been the most fearsome winter in Alaska's history, and it just won't quit.
