Narrative:

I was giving instruction to a student to prepare for his end of course ride for a far 141 school. We had just gone missed off the VOR/DME xx approach at ZZZ. We climbed into the hold at 3;000 and was issued an instruction to climb to 4;000 in the hold. A minute later we were given a traffic callout at our 8 o clock and 10 miles. I called back looking for traffic; but as we were doing turns in the hold it was hard to remember what position the aircraft was in relation to us; although I kept scanning to find it. We completed our teardrop entry into the hold; and as we were about to turn inbound for the first turn in the hold; I spotted an aircraft below me at about 200-300 feet. I theorize because of the position of our wing during the turn in the hold I was unable to see him. I reported the near miss to ATC and talked it over with them once on the ground.
