As a inventory’s nominal share value falls, what occurs to its danger profile? The reply to this query has necessary implications for managing investor expectations and decreasing portfolio turnover. Afterall, traders typically deviate from their chosen long-term methods resulting from emotional reactions to unanticipated market actions. These market-timing actions current their own form of risk, 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 value can’t drop. Others would contend that the inventory will turn into extra delicate to market actions as a result of market circumstances 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 per share. The outcomes might 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 companies going again 50 years. We examined shares that in the course of 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 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 alternative is true of a beta lower than 1.0.
The soar in beta to 1.57 from 0.93 for the shares that dipped beneath the $1 threshold represents a big shift in danger profiles. In reality, it’s statistically important 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 damaging 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 larger 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:
| Beta Earlier than Value Drop | Beta 2 Years After Value Drop | |
| Common Value 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 larger than 1.0 | 1.95 | 1.88 |
| Beta Earlier than Value Drop | Beta 2 Years After Value Drop | |
| Common Value 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 larger than 1.0 | 1.90 | 1.94 |
| Beta Earlier than Value Drop | Beta 2 Years After Value Drop | |
| Common Value 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 larger than 1.0 | 2.02 | 2.17 |
The outcomes spotlight that this drastic enhance in danger (volatility) is completely resulting from will increase in systematic danger, i.e., motion with the market index. Notably, these outcomes aren’t 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 totally 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 getting into penny inventory territory.
The outcomes help the concept that penny shares turn into 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).
