On its first trading day post-stock split, shares of internet retail giant Amazon (AMZN 1.99%) got a lift, rising 2.4% through 3 p.m. ET.

What happened

What happened

With Amazon making the curious decision to split its stock 20 for 1 in March, and that split having finally taken effect today, all investor eyes were on how Wall Street would react to the new share price, and what new price targets analysts would assign to the stock at its new price.

So what?

So what?

As Street Insider reports, the first analyst to put out a report (and a target price) on Amazon post-split was MKM Partners, and MKM is sticking pretty close to its pre-split target price of $3,625 per share (now divided by 20).

To be precise, MKM now values Amazon shares at $180 apiece, only a tiny bit below where it had the stock valued previously

and that bit seems to be due to the analyst thinking investors may have crowded into Amazon before the split in hopes of profiting from other investors buying the stock after the split, once the stock began looking more affordable.

Separately, investment banker Stifel put out a new $190 price target on Amazon shares, reports The Fly, which effectively maintains the banker's pre-split valuation of $3,800, unchanged.
