The first part was already answered only a few posts back. Are you talking about infinite supply, or theoretically infinite volume. They are not the same thing. I'll return to some quotes of from market wizards who are confused just like I am
"After the first serious price break below the base, there will usually be several pullback attempts. The prior base will now
provide an area of overhead supply, as all investors who bought in that zone will be losing money"- William O'Neil
"It is a case of supply and demand: Because
you have more supply, it takes a lot more money to move those stocks." -Ryan
"Demand got bigger and bigger, while at the same time, the supply was going down. You would have had a great bull market in gold in the 1970s, no matter what. Even if inflation was at zero percent, you still would have had a
big bull market in gold during the 1970s, because of supply and demand." - Jim Rogers
"So the markets today are basically the same as the markets in the 1970s, 1960s, and 1950s? The same as the markets in the nineteenth century. The same things make markets go up and down. They have not changed the rules of supply and demand."- Rogers
