Second-Spike Research Notes
The monitor is built around a narrow research question: after a small NASDAQ Capital Market stock has already produced one event-driven price spike, which names have pulled back far enough to be worth watching for a possible second wave? The site does not try to forecast every mover in the market. It focuses on a smaller pattern where catalyst timing, volume, liquidity, and post-spike price behavior can be compared across many tickers with the same rules.
A typical first-spike setup starts with a public catalyst such as an earnings-related 8-K, a foreign issuer 6-K, a periodic filing, an ownership disclosure, or a registration statement that creates a clear event date. The price then moves sharply on unusual volume. After that initial move, many stocks fade quickly. The research value comes from separating ordinary fades from cases where the stock returns toward a prior base, volume contracts, and the price stops collapsing. Those later conditions matter more than the headline alone.
Why Pullback Depth Matters
A second-spike watchlist should not simply rank the largest daily gainers. The first spike often attracts short-term traders, creates crowded entries, and leaves a poor risk profile immediately after the move. Pullback depth helps identify whether that first wave has already cooled off. The monitor compares the post-spike price with the spike high and the pre-spike base. A candidate that has pulled back toward the earlier base can be easier to evaluate than a stock still extended far above its prior range.
This is also why the system can ignore a stock that looks exciting on the day of the first explosion. A large move on fresh volume is useful context, but it is not automatically a second-spike candidate. The model waits for a later structure: enough price decline to reduce extension, enough volume contraction to show the initial chase may be fading, and enough stabilization to avoid ranking names that are still breaking lower without support.
Liquidity And Price Filters
Liquidity is a core control because very low-priced or thinly traded securities can show extreme percentage moves from small order flow. The monitor applies minimum price and dollar-volume checks to the main candidate list. It also keeps a separate high-risk squeeze watch for low-priced 6-K and 13G movers. That separation is intentional. A low-priced stock with a large ownership disclosure and sudden volume may be worth monitoring, but it should not be presented as equivalent to a higher-quality pullback candidate that passes the core model filters.
Volume is interpreted in relation to recent history rather than as a raw share count. A million shares may be ordinary for one ticker and highly unusual for another. The scanner compares current volume with a recent average so that a move can be judged against the stock's own baseline. This makes the output more consistent across companies with very different share counts and trading histories.
Reverse Split Exclusion
Reverse split activity is excluded from the main research output for one month. Reverse splits can create distorted charts, adjusted historical prices, misleading percentage moves, and unusual post-split liquidity. A stock that appears to have made a dramatic move after a reverse split may be reflecting mechanical price adjustment, a changed float, or unstable trading conditions rather than a clean catalyst-and-pullback setup. The monitor treats that as a separate risk category and removes those tickers from the main candidate pool and the squeeze watch during the recent split window.
The rule is deliberately simple: if a ticker has a reverse split event in the prior 30 days, it is excluded from the current scan. This avoids overfitting and keeps the output easier to audit. It also reduces the chance that adjusted chart data creates false positives in the exact small-cap area where reverse splits are common.
SEC Filing Context
SEC filings are not treated equally. An 8-K may describe earnings, contracts, financing, leadership changes, or other material events. A 6-K can be a foreign issuer current report with very different substance depending on the attached exhibit. Schedule 13G and 13G/A filings show beneficial ownership context, but they are not automatically operating improvements. S-1, S-3, and prospectus filings may signal possible issuance or resale pressure. The scanner uses the filing type and text themes as structured input, then applies explicit risk flags when the catalyst may be speculative or dilutive.
The practical use of the site is therefore screening, not decision making. Each row should be checked against the original SEC filing, the latest company news, the current quote, and the user's own risk limits. Small-cap securities can gap, halt, reverse, or lose liquidity quickly. The score is a ranking aid for research workflow; it is not an instruction to buy, sell, short, or hold any security.
