My black dot signal occurs when a stock has been short term oversold and then closes above its 30 day or exp21 day averages. Buying an oversold bounce is minimal risk for me. If the bounce fails I can quickly exit with a small loss. I prefer this strategy to buying break-outs. It works best for me with up-trending stocks near all-time highs.
Look at the new DELL.
GNRC has been consolidating its huge February gain after earnings. After 4 black and one green dot it may be getting ready to move up. The dots indicate bounces from oversold levels. Earnings are projected to grow +32% in 2021 and it has an IBD composite rating of 98 and an EPS rating of 95, ROE=34%.
Finding support at 10 week average, purple dotted line. Clearly a Yellow Band stock since its GLB in July.
