BNS Pops 1.9% on Earnings—But Does History Signal More Volatility?
Bank of Nova Scotia (BNS) unveiled its latest earnings results today, and the stock reacted with a +1.9% move, recently quoted at $69.82. While that uptick bested options market expectations—implied volatility signaled a ±3.7% swing—anyone betting on an outsized post-earnings jump was left wanting more. But as today’s buzz dies down, investors might want to ask: What typically happens after a BNS earnings report?
Peeling Back the Data: BNS Historical Earnings-Day Moves
If you’re wondering whether today’s rally is par for the course or a statistical outlier, let’s dig into the numbers. Over the past 12 quarters, BNS shares have, on average, fallen slightly by -0.3% on earnings days. Only 41.7% of those days closed positive, while 58.3% closed negative—making green closes more the exception than the rule.
The typical gap at the open averaged -0.7%, skewed to the downside in 66.7% of cases. Yet from open to close, the stock did a near coin flip: an average gain of +0.4%, with a 50/50 split between gains and losses. In other words, big surprises are rare—but there is some tendency for the stock to bounce intraday, especially to the upside, as the average high of the day was +1.8% above the open, compared to -1.4% to the downside.
| Stock Performance | Earnings Move | Open Gap | Open to High | Open to Low | Open to Close |
|---|---|---|---|---|---|
| Average Return | -0.3% | -0.7% | +1.8% | -1.4% | +0.4% |
| % of Moves Up | 41.7% | 33.3% | 50.0% | ||
| % of Moves Down | 58.3% | 66.7% | 50.0% |

Absolute Returns: When Does BNS Move the Most?
Those looking for outsized moves should note: The largest absolute earnings-day return in recent years was 7.1%, but the typical move (absolute average return) is a much tamer 3.1%. Even intraday swings (from open to high or open to low) rarely exceeded 4-4.5%. So, if you’re hoping for a fireworks show on BNS earnings day, the data suggests patience may be a virtue.
| Stock Performance | Earnings Move | Open Gap | Open to High | Open to Low | Open to Close |
|---|---|---|---|---|---|
| Absolute Average Return | 3.1% | 1.7% | 1.8% | 1.4% | 2.1% |
| Max Absolute Return | 7.1% | 4.9% | 4.0% | 4.5% | 4.3% |
| Min Absolute Return | 0.2% | 0.1% | 0.0% | 0.0% | 0.2% |
What Happens After the Earnings Dust Settles?
Let’s say you miss the initial move. Is there still money to be made? Historically, BNS stock posts an average gain of +0.3% the day after earnings, rising 66.7% of the time. The gains keep coming (albeit slowly) for the next three days (+1.4% average by day three), before leveling off to a modest +0.6% after two weeks. Short-term post-earnings bulls seem to have the upper hand, at least more often than not.
| Stock Performance | 1 Day After Earnings | 2 Days After Earnings | 3 Days After Earnings | 1 Week After Earnings | 2 Weeks After Earnings |
|---|---|---|---|---|---|
| Average Return | +0.3% | +0.9% | +1.4% | +0.4% | +0.6% |
| % of Moves Up | 66.7% | 58.3% | 58.3% | 66.7% | 50.0% |
| % of Moves Down | 33.3% | 41.7% | 41.7% | 33.3% | 50.0% |
Options Action: A Closer Look at Today’s Most Actively Traded Contract
In the options pits, today's standout trade was the December 2025 $72.5 Call, which saw the heaviest single-leg action with 177 contracts changing hands—perhaps a bet on higher prices or a simple hedge, but worth watching as sentiment builds around future earnings cycles.
| Option Contract | 19-Dec-25 72.5 C |
|---|---|
| Volume | 177 |
| VWAP Price | 0.15 |
| Open Interest | 857 |
| Yesterday's Closing Price | 0.23 |
Final Takeaway: Will the Trend Break?
Today’s post-earnings bounce is right in line with (or slightly better than) historical averages, but BNS’s tendency to drift or reverse after the first move suggests it pays to watch for second-day or intraday swings. And while big post-earnings moves are uncommon, the market’s modest expectations might open the door for surprises, especially if future results deviate from the script.
