Wealth Within analysts Filip Tortevski and Pedro Banales highlighted three companies sitting at key technical levels that traders should closely monitor.

Hear from all the ASX-listed companies that were at the RIU Resources Round-Up in Sydney, right here on HotCopper.com. Over a dozen interviews here.

Dyno Nobel (ASX:DNL) is benefiting from strong demand in the mining explosives sector and improving margins after exiting its fertiliser division. Analysts identified $2.90 as the key breakout level that has now turned into support, while the major upside resistance sits near $4.20. Buyers aggressively defended the stock during recent market weakness, reinforcing the bullish setup.

Steadfast Group (ASX:SDF) is shaping up as a higher-risk reversal opportunity after correcting more than 40% from its highs. The stock recently held its long-term momentum support near $4.00, with analysts watching for a breakout above the $4.30–$4.40 zone to confirm a potential recovery toward $5.40 resistance.

Reliance Worldwide Corp (ASX:RWC) is trading near major historical support around $2.80–$2.90, a level that has repeatedly triggered strong rebounds in the past. Analysts are watching for a breakout above $3.70 to confirm renewed momentum, with long-term resistance sitting near $6.

The analysts emphasised that technical confirmation, disciplined risk management, and waiting for momentum breakouts remain critical before entering these mid-cap opportunities.
