As September comes to a close, Netflix's stock price is falling like the Autumn leaves.

The company's stock lost another 11% on Thursday, racking up one of the biggest drops of the day on Nasdaq as investors reacted to Amazon's flurry of announcements on Wednesday — particularly Amazon's offer of a free month of its Prime streaming service.

Unless the stock makes a dramatic comeback on Friday, Netflix is set to lose about 50% of its value for the month. Of course, Netflix has itself to blame for some of its woes. The company's baffling decision to spin off and rename its DVD service as Qwikster didn't go down well with investors or consumers. Nor did a price hike that took effect on September 1. Here's hoping October looks a little less scary.
