Why do people keep saying that we're in a stock market bubble, just because the market happens to be rising a bit faster than normal?

The only "people" saying anything is you.  It is a bubble, it is NOT a bubble, it is rising a bit faster, it is NOT rising a bit faster.  They are fighting the Fed, they are NOT fighting the Fed.  This time it is truly different, this time it is NOT truly different.  Or did all that escape your eagle eye attention?

Because the FED cannot be blamed for everything. That is neoliberal hysteria and scapegoating. And stock market bubbles have happened many times.

Depending on who you talk to, there is Always a 'Bubble'. 

Why are companies in business?  To make money.  So the only important indicator is the Price/Earnings ratio.  The ratio is somewhere around 23 now which is very high historically.  Either earnings will increase dramatically (not) or prices will return to normal levels. 

A lot of money circulating, which is different from many using their currency, but it is good in the short term, but bad in the long run.

maybe someone told them that

If you put $30 into the stock market, you'd only get back $1 in profits in a year. Historically, you'd only need to put $10 into the market to get $1 back in a year. This is the biggest most over inflated bubble in world history.
