As a inventory’s nominal share worth falls, what occurs to its threat profile? The reply to this query has essential implications for managing investor expectations and decreasing 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 threat, including to the prevailing threat of unpredictable markets.
Some would argue that as a inventory approaches the decrease finish of penny inventory territory, volatility will average as a result of there’s an inherent threshold beneath which the value can’t drop. Others would contend that the inventory will turn out to be extra delicate to market actions as a result of market circumstances dictate the survival of the corporate.
We investigated what occurs to systematic threat and the whole volatility of a inventory when it turns into a penny inventory, i.e., its worth drops beneath $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 whole volatility will increase accordingly.
We pulled inventory returns on all NASDAQ- and NYSE-listed corporations going again 50 years. We examined shares that in the course of the 50-year interval crossed the edge of $1 a share, $2.50 a share, or $5 a share. We captured the situations when every inventory crossed these thresholds for the primary time. We then famous the beta of the shares earlier than the edge 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 worth is extra risky than the general market, i.e., its worth swings extra wildly. The alternative is true of a beta lower than 1.0.
The leap in beta to 1.57 from 0.93 for the shares that dipped beneath the $1 threshold represents a major shift in threat profiles. In reality, it’s statistically important at 1%. On the $1 threshold, the typical penny inventory has far more systematic threat and whole volatility. And this shift is throughout the board. Shares with destructive 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 greater than 1.0 go from 1.95 to 1.88.
What occurs to systematic threat and the whole volatility of a inventory when it turns into a penny inventory:
| Beta Earlier than Worth Drop | Beta 2 Years After Worth Drop | |
| Common Worth Drop Cutoff: $1/share | 0.93 | 1.57 |
| Beta beneath 0 | -0.62 | 1.14 |
| Beta between 0 and 1.0 | 0.55 | 1.37 |
| Beta greater than 1.0 | 1.95 | 1.88 |
| Beta Earlier than Worth Drop | Beta 2 Years After Worth Drop | |
| Common Worth Drop Cutoff: $2.50/share | 0.90 | 1.56 |
| Beta beneath 0 | -0.55 | 1.01 |
| Beta between 0 and 1.0 | 0.52 | 1.27 |
| Beta greater than 1.0 | 1.90 | 1.94 |
| Beta Earlier than Worth Drop | Beta 2 Years After Worth Drop | |
| Common Worth Drop Cutoff: $5/share | 1.00 | 1.07 |
| Beta beneath 0 | -0.56 | -0.51 |
| Beta between 0 and 1.0 | 0.47 | 0.50 |
| Beta greater than 1.0 | 2.02 | 2.17 |
The outcomes spotlight that this drastic enhance in threat (volatility) is solely as a consequence of will increase in systematic threat, 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 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 as a result of inventory coming into penny inventory territory.
The outcomes assist the concept penny shares turn out to be far more dangerous (greater volatility) as they method the zero-price barrier and that this threat is because of will increase in systematic threat (elevated sensitivity to market actions).
