3 ASX 200 shares at 52-week lows
Sigma Healthcare Ltd (ASX: SIG)
This ASX 200 healthcare share fell to a 52-week low of $2.70 on Tuesday.
The stock has come off by 7.5% after reaching heady levels last year due to the Chemist Warehouse merger.
Morgans thinks Sigma Healthcare shares are still worth buying, but cautiously.
The broker downgraded its rating from buy to accumulate after going through Sigma's 1H FY26 report.
In a note, Morgans said:
SIG posted a solid 1H26, which was in line with consensus.
The highlights included solid CW LFL sales growth (up 15%), revenue growth higher than cost growth by 4.5%, and synergy targets on track.
We move to an ACCUMULATE (was Buy) due to YTD share price strength.
Morgans reduced its 12-month price target from $3.39 to $3.36.
Reliance Worldwide Corp Ltd (ASX: RWC)
The Reliance Worldwide share price fell to a 52-week low of $3.13 on Tuesday.
The ASX 200 industrial share has pulled back 35% over the past 12 months.
Morgans maintained a hold rating on the stock after reviewing the company's 1H FY26 report.
The broker commented:
RWC's 1H26 result was below expectations, impacted by ongoing subdued housing conditions in all regions and higher costs, particularly in relation to US tariffs.
Management anticipates trading conditions in 2H26 to remain broadly consistent with 1H26, albeit US tariff mitigation strategies and the roll-off of some costs should see an uplift in margins.
Longer term, RWC aims to reduce its exposure to copper price volatility by substituting copper with alternative materials such as plastic and stainless steel.
The company's new operations in Poland and Mexico will also help lower costs and provide manufacturing flexibility.
Morgans said it prefers "to wait for clearer signs of an improvement in housing conditions before reconsidering our view".
The broker slashed its 12-month price target from $4.50 to $3.65.
Nine Entertainment Co. Holdings Ltd (ASX: NEC)
This ASX 200 communications share fell to a 52-week low of 99 cents yesterday.
That's a 40% fall over 12 months.
Following the media giant's 1H FY26 report, Morgan Stanley reiterated its buy rating on Nine Entertainment shares with a $1.40 target.
UBS kept its hold rating on the stock and lowered its price target from $1.22 to $1.13.
