Quantiative Easing fuels stock markets, but why? 
There's a premium or discount for various stocks subject to influence by the alternatives available to investors, meaning investments are susceptible to the principle of supply and demand. This is easily seen when industries or business models get hot, and everybody wants a tech company, a social media company, or a solar company in his portfolio.  You'll see bubbles like the dotcom bubble, the RE bubble, etc., as people start to think that the industry and not its performance are all that matters.  The stock price of a desired industry or company is inflated beyond what might otherwise be expected, to accommodate the premium that the investment can demand. So if bonds become uniformly less attractive in terms of returns, and certain institutional investors are largely obliged to continue purchasing them anyway, then flexible investors will need to look elsewhere.  As more people want to buy stocks, the price rises.  Supply and demand is sometimes so elementary it feels nearly counter-intuitive, but it applies here as elsewhere.
