In the short time period since the Twitter IPO its stock price has performed as if it was riding a roller coaster. Various factors have contributed to its meteoric rise to a peak, followed by a rapid decline. Market factors unrelated to the fair market value of Twitter shares have influenced the price movement. Prior to the Twitter offering, IPOs were in a state of great demand (which occurs from time-to-time) with investors of most IPOs being allocated less shares than requested. Many investors were purchasing the unallocated portion of their subscription as soon as the IPO commenced trading. The Twitter offering was highly glamorized by the financial press. Twitter shares like those of many other IPOs immediately skyrocketed in price. Twitter has many loyal users who were unable to obtain an allotment on the IPO and they and other investors for various reasons elected to buy the shares in the after market. Chart theorists added fuel to the fire as they determined buy points as the Twitter stock price rose and gathered momentum. As the stock price rose far above the IPO price it attracted short sellers. However, as ofter occurs when short sellers sell into a rapidly rising market, they get squeezed and panic, one-at -a-time, and cover their shorts at ever increasing prices, thereby driving the stock price higher.
When the price of Twitter shares peaked and started to decline, various factors, acting in a manner similar to the way that gravity effects a roller coaster car, precipitated the decline. Some analysts withdrew their support based upon market capitalization and recommended sale . Stop loss orders, which have become fashionable and which were placed at various levels during the share price increase, began to be executed at declining prices, creating selling pressure. Chart theorists interpreted sell signals. Short sellers, who follow the analyst reports, know about the existence of stop loss orders and understand chart theory, exacerbated the decline by selling short at declining prices. As the stock declined, margin calls and tax loss considerations came into play and some unsophisticated stockholders sold in panic.
Like a roller coaster the ride will stop at the bottom. If Twitter can generate revenues and profitability from its large number of followers, its shares will begin to rise again. If, as I expect, the rise occurs, the SEC should conduct an investigation as to when every short sale took place to try to determine the role of short selling in exaggerating stock market declines.
