Does a Stock’s Price Influence Its Risk Profile?

As a inventory’s nominal share worth falls, what occurs to its danger profile? The reply to this query has vital implications for managing investor expectations and decreasing portfolio turnover. Afterall, buyers usually deviate from their chosen long-term methods as a result of emotional reactions to unanticipated market actions. These market-timing actions current their very own type of danger, including to the present danger of unpredictable markets.

Some would argue that as a inventory approaches the decrease finish of penny inventory territory, volatility will reasonable as a result of there may be an inherent threshold under which the value can not drop. Others would contend that the inventory will turn out to be extra delicate to market actions as a result of market situations dictate the survival of the corporate.

We investigated what occurs to systematic danger and the whole volatility of a inventory when it turns into a penny inventory, i.e., its worth drops under $5 per share. The outcomes could shock you. We discovered that as a inventory declines in worth, it turns into extra delicate to market actions. In different phrases, its beta will increase and its complete volatility will increase accordingly.

We pulled inventory returns on all NASDAQ- and NYSE-listed corporations going again 50 years. We examined shares that throughout the 50-year interval crossed the brink of $1 a share, $2.50 a share, or $5 a share. We captured the cases when every inventory crossed these thresholds for the primary time. We then famous the beta of the shares earlier than the brink crossovers and in contrast them to the identical betas of the shares two years after the crossover date.

The Findings

The primary attention-grabbing discovering is that when a inventory dips under the $1 threshold, on common, its beta goes from 0.93 to 1.57. A beta higher than 1.0 means a inventory’s worth is extra unstable than the general market, i.e., its worth swings extra wildly. The alternative is true of a beta lower than 1.0.

The bounce in beta to 1.57 from 0.93 for the shares that dipped under the $1 threshold represents a major shift in danger profiles. The truth is, it’s statistically vital at 1%. On the $1 threshold, the common penny inventory has far more systematic danger and complete volatility. And this shift is throughout the board. Shares with unfavourable betas go from a median of -0.62 to 1.14. Shares with betas between 0 and 1.0 go from 0.55 to 1.37. And shares with betas increased than 1.0 go from 1.95 to 1.88.

What occurs to systematic danger and the whole volatility of a inventory when it turns into a penny inventory:

The outcomes spotlight that this drastic improve in danger (volatility) is completely as a result of will increase in systematic danger, i.e., motion with the market index. Notably, these outcomes should not pushed by a reversion to the imply over time in betas.

On the excessive finish of our examine, we examined when shares cross the $5 a share barrier. The outcomes look fairly completely different. Earlier than a inventory crossed the $5 threshold, on common, its beta is 1.0 and afterward it’s 1.07.  The opposite beta tiers at $5 a share confirmed the identical outcomes. This affirms that the $1 threshold outcomes are really as a result of inventory coming into penny inventory territory.

The outcomes help the concept that penny shares turn out to be far more dangerous (increased volatility) as they strategy the zero-price barrier and that this danger is because of will increase in systematic danger (elevated sensitivity to market actions).
