Last time such inverse ( ) signal was back 15th of Jan with massive price drop (marked with arrow on chart).
This doesn't mean we will have strong bull run yet because this cross we have below Kumo Cloud. But still this might signal for trend reversal already.
Also you can see Kijun-Sen base line acting as support during end of Dec and early Jan.
Hopefuly today candle closes green with nice hammer shape, which is reversal candle at such set-up.
