The key to growth of a company is 'return on capital'. Many firms that are capital hungry usually have self sustainable growth rates far below the growth rates that their internal growth can afford. They usually end up raising a lot of debt or diluting equity (Capital = Debt + Equity). As an investor, increasing debt and increasing dilution of equity will hurt the ROCE of the company making it less attractive for investment. Hence people don't flock to invest in capital hungry companies.
