As a inventory’s nominal share value drops, what occurs to its danger profile? The reply to this query has necessary implications for managing investor expectations and lowering portfolio turnover. Afterall, buyers typically deviate from their chosen long-term methods as a consequence 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 beneath which the worth can’t 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 value drops beneath $5 a share. The outcomes could shock you. We discovered that as a inventory falls in worth, it turns into extra delicate to market actions. In different phrases, its beta will increase and its whole volatility will increase accordingly.

We pulled inventory returns on all NASDAQ- and NYSE-listed companies going again 50 years. We examined shares that throughout the 50-year knowledge set 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 fascinating discovering is that when a inventory dips beneath the $1 threshold, on common, its beta goes from 0.93 to 1.57. A beta higher than 1.0 means a inventory’s value is extra unstable than the general market, i.e., its value swings extra wildly. The other is true of a beta lower than 1.0.

The bounce in beta to 1.57 from 0.93 for the shares that dipped beneath the $1 threshold represents a major shift in danger profiles. In truth, it’s statistically vital at 1%. On the $1 threshold, the common penny inventory has way more systematic danger and whole volatility. And this shift is throughout the board. Shares with detrimental betas go from a mean 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 larger than 1.0 go from 1.95 to 1.88.

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

On the excessive finish of our research, 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 because of the inventory getting into penny inventory territory.

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